TIRE-FASTENING DEVICE.

Specification of Letters Patent.

Patented Apr. a, rare.

Application filed May 27, 1912. Serial No. 699,965.

To all whom it may concern:

Be it known that I, FRANK P. JOHNSON, a citizen of the United States, residing at Danville, in the county of Montour and State of Pennsylvania, have invented a new and useful Tire-Fastening Device, of which the following is a specification.

The invention relates to improvements in the fastening devices.

The object of the present invention is to improve the construction of tire fastening devices, and to provide a simple, safe and efiicient tire fastening device of inexpensive construction designed for securing a pneumatic tire of the detachable type to the rim of anautomobile or other vehicle wheel, and enabling a pneumatic. tire to be easily and quickly removed when it is desired to replace or repair an inner tube.

A further object of the invention is to provide a device for the purpose stated which shall be proof against accidental disconnection, and which when the tire is removed from the rim will remain on the rim so that the parts maymot be lost nor mislaid, and which may be readily operated without the use of any special tools.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claims.

hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing I Figure l is a side elevation of a portion of a wheel equipped with a tire fastening device, constructed in accordance with this invention.

Like numerals of reference designate corresponding parts' in all the figures of the drawing. I

In the accompanying drawing in which is illustrated the preferred embodiment of the invention, 1 designates a rim constructed of metal and secured by any suitable means to a wooden felly 2. The felly 2 is connected with the outer ends of spokes 3 of an automobile or other vehicle wheel, which maybe of any preferred construction. The rim 1, which is cylindrical, is provided at one of its side edges with an integral circumferential flange 4, having a groove 5 in its inner face to receive the longitudinal head 6 of the adjacent side of the outer casing or shoe 7 of a pneumatic tire. The head 8 at the opposite side of the outer casing or shoe engages a groove 9 in the. inner side or face of a split ring 10, detachably mounted on the rim and cooperating with the fixed flange 4 in securing the pneumatic tire to the rim. The pneumatic tire, which is of'the clencher type, may be of any preferred con- I struction and has an. innertuhe 11 constructed in the usual manner, and it is equipped with a valve having a stem 12, which eX- tends through registering openings 13 and 14 in the rim 1 and the folly 2 of the Wheel.

The split ring, which is resilient, is constructed of suitable metal and is seated in a circumferential channel or groove 15, formed in the rim adjacent to the side'edge thereof, as clearly illustrated in. Fig. 2 of the drawing. The channel is segmental in cross section, and the inner periphery of the split ring is rounded transversely to fit the same, and said channel or groove being pressed in the rim provides a bead. on the inner face of the-latter. The rim is provided (P n LET,

an approximately T-shaped locking deviceor member for retaining the split ring in the channel and for holding the same in engagement with the fixed transverse lugs 16.

'l he terminal portions of the split ring are, provided at their inner peripheries with notches 21 conforming to the configuration of the lugs and snugly receiving the same and forming radially arranged shoulders for engaging the shoulders of the transverse lugs. -lhe fixed. transverse lugs of the rim and the notches in the iriner periphery of the split ring interlock the latter with the rim and prevent the split ring from creeping or moving longitudinally in the channel 15.

Any other means for interlocking. these two elements and holding them from relative movement would come within the pur view of this invention.

The terminals 22 of the split ring are provided with opposite transverse recesses 23, which extend through the ring from the inner to the outer side, and which when the meeting ends of the ring are-in abutting relation, form a. substantially oblong opening or space to receive the oblong head of the T-shaped locking member. The ends of the split ring below said recesses are cut away a short distance at 2 2, to rovide an entrance or mouth through whic the head of the locking member is passed when applying the ring in place. To permit this the width length is suilicient to span the meeting ends of the ring and be received in the said recesses,23. The locking member below the head is provided with a rounded stem or pivot 25, which is swiveled or journaled in the opening 19 of the rim, radially thereof, and is adapted to be rotated so as to dispose the oblong head longitudinally of the rim, which is the locking position, or transversely of the rim, which 1s the unlocking position. Fig. 4 of the drawing illustrates the two positions o the head in full and dotted lines; it being noted that the locking member rotates on an axis which is radial to the rim. When the locking member is turned to the position shown in dotted lines, its side edges coincide with the ends of the split ring at the cutaway portions 24. This permits the splitring to be passed over the head of the locking device and releases the split ring and'also permits the terminal portions thereor to be sprung out of engagement with the fixed lugs 16 of the rim. When the oblong t5 head of the T-shaped locking member is of the head is less than the entrance 24. Its

areas-ea turned lon 'tudinally of the rim, it is carried into t e recesses 28 and rigidly holds the ring against outward movement, where-- by the split ring is maintained in its interlocked relation with the rim. When the split ring is removed, the outer-casing or shoe and the inner tube maybe readily de tached and replaced.

As a means for turning the locking memher, I have provided an operating handle in the form of a hasp member 26, provided with a cam-shaped head 27 bifurcated to receive the end 28 of the stem and eccentrically pivotedto the same by arivet or pin 29, or other suitable fastening device. The end 28 of the stem orpivot 25is reduced and flattened at opposite sides to form a terminal ear to which the hasp member is pivoted. The pivot 29 of the hasp member extends in the same direction as the major diameter of the oblong head, and when the, head of the locking member extends longitudinally of the rim and is in engagement with the terminal recesses of the split ring, the hasp member is arranged to swing transversely of the wheel into and out of en gagement with the valve stem 12, and it is provided with a circular opening 30 through which the valve stem projects when the beep member is swung inwardly against the inner periphery of the telly, as illustrated in Fig. 2 of the drawing. This inward swinging movement of the hasp member carries the cam-shaped head thereof into contact with the bead on the inner periphery of the rim, and the locking member is thereby drawn downwardly or inwardly into tight engagement with the terminals of. the split ring, which are held firmly against the rim. The'opening 30 is of a diameter'llllh to looselyrcceive the valve stem, which is depressed or forced inwardly to enable the hasp member to be swung into a position, which will permit the outer portion of the valvestem to extend through the opening me 30. it is,:therefore, necessary in order to swing the hasp member outwardly for releasing the split ring to first depress the valve stem and disengage the same from the hasp member. -'lheresiliency of the in- 115 dated inner tube maintains the valve stem in an extended position and will return, the valve stem to such position after the same has been 'pushed inwardly and is'released.

By this construction the valve stem opcrates as a locking device for securing the hasp in its engaging position. The outer portion 31'of the valve stem is threaded and receives a nut 32 and a cap 33 of the ordinary construction. The nut and cap positivcly "fasten thehasp member on the extended portion of the valve stem, but there is no liabilityof the hasp' being thrown out.- ward by jar or vibration and accidentally locking member, even should 13cthe cap and the nut become lost from the threaded .portion of the valve stem. The valve stem is of the usual type.

In some makes of automobiles the double ring construction is employed and the detachable ring of the present invention may be advantageously substituted for the outer ring of such double ring construction. The detachable ring may be constructed with either a straight side to adapt it for a Dunlop tire, or it may be curved to engage with a tire of the clencher type, and if desired a detachable ring may be employed embody.- ing both of these features in' order that it may Le reversible to adapt it for engaging either class of tires.

In Fig. 7 of the drawings, the split tire retaining ring 34 is provided with a smooth,

inner side face 35 to adapt it for use in connection with a Dunlop tire. The detachable ring is also provided at its inner edge with notches 36, and at its ends with reoesses 37 constructed and operated in a manner similar to the notches 21 and the recesses 23 heretofore described.

In Figs. 8 and 9 of the drawings, 38 designates a detachable ring provided at, one side with a smooth face 39 to adapt it for use in. connection with a Dunlop tire, and

having a groove 40 at the opposite side to engage with the tire of the clencher type. The ring 38, which is continuous, is arranged upon the rim 41 at the inner side of the circumferential channel 42, which is adapted for the reception of a split ring 43 having notches 44 at its inner edge to engage with lugs 45 of the rim. The lugs 45 are located in the channel'42 and the ends ofthe detachable ring are retained in engagement with the said lugs 45 by means of a pivoted locking device 46 having a head I 47 for engaging recesses 48 in the ends of the split ring 43.

The split ring 43 retains the ring 38 and the tire on the rim, and the ring 38 is reversible to arrange either its straight side 39 or its grooved side 40 in position for engaging a tire.
